sf6 switchgear evacuation Safe and efficient

Although the contribution of SF6 emissions from gas-insulated medium voltage switchgear (MV GIS) to man-made global warming is very small, an eco-efficient insulating gas will contribute to a reduction in the carbon footprint of the electricity grid. In addition, reporting and monitoring will be simplified.
